Answer:
The reaction is favorable at all temperatures
Explanation:
Since G = H - TS, -H and +S would result in G = -H -TS, which will always be negative.
Answer:
B
Explanation:
Mass number = number of neutrons + number of protons
Atomic number is the number of protons in the nucleus.
58Ni : 58 is the number of neutrons + number of protons
atomic number of Ni is 28. Thus, 58 -28 = 30 neutrons
57Co ; 57 is the number of neutrons + number of protons
number of Co is 27. Thus, 57 – 27 = 30 neutrons
3Mg + 2H3(PO4) —> Mg3(PO4)2 + 3H2
I think
lighting a candle, An initial input of energy causes oxygen and wax react to produce carbon dioxide, water, and heat.
Explanation:
During an exothermic reaction, energy is constantly given off, often in the form of heat, combustion is the best example of this
